Huawei has offered to give the Australian government "unrestricted" access to the firm's software source code and hardware equipment in an effort to dispel security fears, months after the Chinese telecoms giant was barred from supplying infrastructure equipment for the country's national broadband network.

Both Huawei and ZTE, another Chinese telecoms equipment maker, came under fire this month from the U.S. House Intelligence committee after lawmakers said U.S. businesses should not use technology from the two Chinese companies, as it could pose a "national security threat."

In a 52-page report, the committee said the two Chinese giants did not fully address their concerns. "Neither company was forthcoming with detailed information about its formal relationships or regulatory interaction with Chinese authorities. Neither company provided specific details about the precise role of each company's Chinese Communist Party Committee," the report said.

However, a subsequent White House report appeared to refute the U.S. House committee's fears , saying it had conducted a review that found "no clear evidence of spying" by Huawei, according to Reuters. However, the White House denied that any such investigation took place.
